Development and Evaluation of a Broad spectrum Polyherbal Sunscreen formulation using Solid Lipid Nanoparticles of Safranal.

The significant inhibitory activity of Safranal on matrix metalloproteinases (MMPs) analyzed by biochemical investigation method and a higher SPF established that this bioorganic molecule is a strong photoprotective agent. Designing solid lipid nanoparticles and incorporation of other traditional ingredients in the recipe augmented its antisolar property and provided an all natural sunscreen.
